I'm not sure if it helps the hair to grow quicker or not, but it helps with the quality of your hair. Usually throughout pregnancy my hair is fantastic, but with this one it is terrible... I am losing it by the handful (thankfully it is already really thick) and it is dry & dull. I have only used the Nioxin twice and I don't know if it is my imaginiation or not, but I don't seem to be losing as much hair already. I am definitely going to go buy the proper stuff today
There is a website if you're interested... just google Nioxin.
